Objective:
To investigate time trends in dental service provision.
Methods:
A random sample of Australian dentists was surveyed by mailed questionnaires in 1983-1984, 1993-1994, 2003-2004, and 2009-2010 (response rates 67-76%). The service rate per visit was collected from a log of services.
Results:
The rate of service provision per visit [rate ratio (RR)] increased from 1983-1984 to 2009-2010 for the service areas of diagnostic (RR=1.8; 1.6-1.9), preventive (RR=1.9; 1.6-2.1), endodontic (RR=2.1; 1.7-2.6), and crown and bridge (RR=2.9; 2.3-3.8), whereas prosthodontic services decreased (RR=0.7; 0.6-0.9).
Conclusions:
The profile of services provided by dentists changed over the study period to include less emphasis on replacement of teeth and more on diagnosis, prevention, and retention of natural dentitions.
